Which statement is true?

Answers

Answer:

Step-by-step explanation:

x-intercept -> when y = 0

f(x) x-intercept -> (1 , 0)

g(x) x-intercept -> (-1 , 0)

y-intercept -> when x = 0

f(x) y-intercept -> (0 , -1)

g(x) y-intercept -> (0 , 1)

The x-intercept of f(x) is greater than the x-intercept of g(x)

The y-intercept of g(x) is greater than the y-intercept of f(x)

So from the options, the answer is D. The x-intercept of f(x) is greater than the x-intercept of g(x)

In quadrilateral RSTU in the coordinate plane, RS | TU and RS = 6. Which additional statement allows you to conclude that RSTU is a
parallelogram?

Answers

Answer:

A. ST = RU

Step-by-step explanation:

Quadrilaterals are four sided figures. Examples are: square, rectangle, trapezium, parallelogram etc. A parallelogram is a quadrilateral that has equal opposite and parallel sides.

This implies that in the given question since RS || TU, then;

RS = TU = 6

So that for RSTU to be a parallelogram,

ST = RU

Thus, the appropriate option to the question is A.

A meal that cost $50 had a 20% tip and 5% sales tax. How could you calculate your final total bill?

Answers

Answer:

$57.50

Step-by-step explanation:

find 10% of 50 first, which is 5, because 5 × 10 = 50, then add $10 to the $50 beacause 50 × 0.2 = 10, next, remove 5%, to do this divide 10% by 2 to get $2.50, 60 - 2.5 = 57.5

Compare Texas to Carolina. Write the answer in scientific notation. Texas= 2.5x10 to the power of 5. Carolina= 1.2x10 to the power of 3.

Answers

Answer:

Texas is 2.08333 * 10^2 times the size of Carolina.

Step-by-step explanation:

Given :

Given that:

Texas= 2.5x10^5

Carolina = 1.2x10^3

Comparing the size of Texas and Carolina

Texas / Carolina

(2.5 * 10^5) ÷ 1.2 * 10^3

(2.5/1.2) * 10^5-3

2.08333 * 10^2

Hence, Texas is 2.08333 * 10^2 times the size of Carolina.

Answer:

Step-by-step explanation:

−5x + y = −3
3x − 8y = 24

Answers

Answer:

x = 0

y = -3

Step-by-step explanation:

-5x + y = -3 --------------(I)

3x - 8y = 24 ------------(II)

Multiply the equation (I) by 8

(I)*8    - 40x + 8y = -24

(II)         3x -  8y   =  24   {Add and y will be eliminated}

           -37x          = 0

                     x     = 0

Plugin x = 0  in equation(I)

-5*0 + y = -3

     0 + y = -3

           y = -3

Answer:

- 5x + y =-3    ......1

3x -8y = 24.........2

eqn 1 is multiply by 8 .we get -40 x +8y=-24 .....3

-40 x +8 y =-24 ...........3

3 x   - 8y  = 24     ......... 2

·································

-37 x +0 = 0

··························

x =0

put x = 0 in equation 2

3 x -8 y =24

3×0 -8 y = 24

0 -8 y=24

-y =24÷8

-y =3

y = -3

ans ;

x = 0

y = -3

The price increased by 64.5, which makes a total of 279.5

Step-by-step explanation:

215*0.30 = 64.5

215 + 64.5 = 279.5

0.30 = 30% of 100

When you multiply by 0.30 you get 30%, or with any decimals, like multiply by 0.50 to get 50% of something, etc.

a large painting has a length of 18 inches and width of 12 inches. If each dimension is reduced by x inches to make the ratio of length to width 5 to 3, what is the value of x

Answers

Answer:

The value of x = 3.

Step-by-step explanation:

The ratio between length and width is given by:

[tex]\frac{L}{W}=\frac{5}{3}[/tex]

Where:

L represents the new length W represents the new width

Now, we know that each dimension is reduced by x inches, it means:

[tex]L=18-x[/tex]

[tex]W=12-x[/tex]

Then, we will have:

[tex]\frac{18-x}{12-x}=\frac{5}{3}[/tex]

Finally, we just need to solve it for x.  

[tex]3(18-x)=5(12-x)[/tex]

[tex]5x-3x=60-54[/tex]

[tex]2x=6[/tex]

[tex]x=3[/tex]

Therefore, the value of x = 3.

I hope it helps you!
